:T0 allwhom itmmg concern;

Be it known that I, J ENS THEQDORSUHR SCHOUBoE,'-'first lieutenant asubject ofthe The present invention refers to a recoil mechanism inself-loading pistols with-fixed barrels characterized thereby that thebreechblock is in one piece with a- U-shaped receiver,-

King of Denmark, residing at Rungsted Ladegaard, Rungsted, Denmark,'haveinvented a new and nseful Recoil Mechanism in Self- Loading Pistols withFixed Barrels, of which the following isa specification.

which during-the backward and f or-ward movement of: the breech-blockcompletely covers thelock mechanism and at the same time, to: getherwith a closing-piece,'forms the connection between the main parts .ofthe pistol;

* the said receiver being inside supplied. with grooves-which gearpartly with projections in the barrel extension firmly connected withthe barrel and which in its turn .inknown manner is connected with thehandle and partly with projections on the closing-piece,

which is forced rearward by the recoil-spring and held by hooks in thehandle, while it at,

- the same time with its foot rests upon the top j is thereby kept inplace. g

, The invention is shown on the accompanyof the rear end of the barrelextension, which ing drawings, wherein- Figure l is a vertical sectionof the entire mechanism. Fig. '2 shows the recoil mechanism and thepositions of the various parts at the endof the recoil. Fig. 3 is abottom plan view of the receiver, with the breech-block. Fig. 4 shows asection on the line 111 of Fig. 3. Fig; 5 shows a section-on the lineIIY'II of Fig.3. Fig. 6 is a side view of the closingpiece. Fig. 7 showsa section on theline III arranged magazine 4, hammer .5, trigger ar- IIIof Fig. 6.

Fig.8 is an under side view of-the closing-piece. Fig. 9 is a bottomplan of the" breech end of the barrel and the barrel extension. Fig. 10shows the back part of the cover and of the pistol with the closingpiecepressed inward, so' that the pistol can *bedismembered. l

. The pistol consists oi the barrel 1, firmly connected with the barrelextension 2, which in known manner is connected to the handle Inthishandle there is in known manner rangemeut 6, and the appurtenantsprings. 0n the sides of the barrel extension are ribs 7.

'Thehandl'e is in the'rear finished off with two breech-block is a borinfor the firing-pin 1 1 and above this a boring for the recoil-spring 15.Thejiring-pin is held in place by a book 16, actuated by therecoil-spring or in any othersuitable way. That part of the recoilspringwhich lies outside the boring is guidedby a pin- 17, firmly fixed'in aclosing-piece 1.8. This latter partise'e Figs. 6, 7, 8) has on the outersides guides 19-,- corresponding to v grooves'20 inside the rear-end ofthe receiver.

(See Fig. 2.) The closing-piece is hollow, and

the foremost" end of this cavity has a rear-- ward projection 21, aroundwhich the hooks 8 will catch when the closing-piece is forced backwardbythe recoil-spring. The closingpiecejends in front and below in a foot23,

which bears against the upper part of the rear of the barrel extension,which thereby is kept in place. Ont'op of the receiver andin the rear isa spring-hook 22, which catches over the upper rim of the closing-piece,

thereby "preventing this from being thrown rearward by the recoil-spring[when the pistol is taken to pieces. This is done in this way that afterthe magazine having been removed the closing piece is with the rightthumb pushed so much forward that the projection 21 shows clear of thehooks 8, (see Fig. 10;) whereupon the left hand presses down upon thebarrel, which is made free, together with barrel-extension, breech-bl0ckwith receiver, and closingpie'ce, so'that the receiver 9 can bedisconnected from the bar rel and barrelextension. If it be desired toseparate the weapon further; the hook 22 is raised .and theclosing-piece and recoil sprin g can be removed.

' the chamber.

The recoil mechanism actsin the following manner: When the pistol isfired, the pressure of the powder-gas will force the breechblock andwith it the receiver rearward, whereby the hammer is recocked, the emptycartridge-case ejected, and a fresh cartridge brought up from themagazine. The recoilspring tightened thereby will again force forwardthe breech-block, whereby the cartridge coming from the magazine isintroduced into The pistol is now again ready for fire In order to cockthe pistol for the first shot, the receiver is with the left handcarried backward and released when brought as far back as it will go.The sides of the receiver are therefore knurled on the outside. Havingnow described my invention, what I claim as new, and desire to secure byLetters Patent, isi 1. In a firearm, the combination with a frame and abarrel carried by said frame, of a receiver, a breech-block connectedtherewith, aclosing-piece at the rear of the frame, a spring between'said receiver and closingpiece, said receiver being adapted to slideonthe frame, substantially as described.

2 In a firearm, the combination of the frame, a barrel carried therebyhaving an extension, a closing-piece resting on the extension of thebarrel and the frame, a projection on the closing-piece,'a hook on theframe engaging therewith, a receiver, a breech-block connectedtherewith, a spring between said receiver and closing-piece, said springkeeping the projection and hook in engagement,said receiver sliding onthe frame and closing-piece, substantially as described.

In a firearm, the combination with a frame and a barrel carried by saidframe, of "a receiver, a breech-block connected therewith, a removableclosing-piece at the rear of the frame, a spring between said receiverand closing-piece and tending to hold the closingpiece normally inposition, the said receiver being adapted to slide on the'frame andclosing-piece, substantially as described.

4. In a firearm, the combination with the frame and a barrel carriedthereby, of a receiver, a closing-piece at the rear of the receiverdetachably connected with the frame and a spring between the receiverand 010s ing-piece for holding the latter in place, substantiall y asdescribed.

5. In a firearm, the combination with a frame and a barrel carried bysaid frame, of a receiver, a removable closing-piece at the rear of theframe, a projection on the closingpiece, a hook on the frame engagingtherewith, said closing-piece having a portion outside of the hook and aportion on the inside of the hook and a spring for keeping theclosing-piece in engagement with the hook, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
